Sweet!
As for the searchable rulings, I've been using the "dump" files to look up things in the rulings that are not in the rulings for some cards, but are for others. For instance, I had a guy argue with me, saying that Ryu Kokki's effect was continuous. I told him that it wasn't and would get him proof AFTER the duel, but as the Head Judge that was my final answer. I couldn't find it under Ryu Kokki, but did under it's counterpart, Getsu Fuhma and printed it out for him.
There are several cards that are like that. The newer ones have the answers, you just have to know which cards to look under.
Antoher instance: A guy argued with me, saying that if Destiny Hero-Plasma is destroyed by an effect (or Book of Moon) chained to his effect attempting to equip another monster, that the targetted monster would not be destroyed. I, again, told him as the Head Judge, he would have to go by my decision, but proof would be waiting him at the judge station after the match. However, I tried Plasma, Relinquished/Restrict. It wasn't until I looked under the rulings for Allure Queen LV3 (not LV5 orLV7 either) that I got my answer.
Those Dump Files have been a HUGE help in my offline judging!! THANKS!
